A scrapped version of the Bioluminescent Dragon.
The Bioluminescent Dragon, or Bio Dragon, is a Kickstarter exclusive dragon with a unique breath unlike any of the standard elements. Its breath will be able to mark other dragons, temporarily giving them a bio-luminescent glow, which the Bioluminescent Dragon itself will constantly have. It will be unable to use damage-dealing attacks. Being one of the smaller dragons, the Bio Dragon will grow faster than most species, reaching adulthood in just 30 minutes.
The Bioluminescent Dragon originally was going to be an amphiptere but somewhere down the line was changed into a wyvern. Eventually, the wyvern model got scrapped and we have no new news on if it will still be a wyvern or if it may change in the future.
